Thermal Boundary Layer Thickness
In order to perform a calculation in free convection, I need a mesh fine enough to render the physical phenomena.
I am using FLUENT by the way.
If I understood well, the center of my first cell should be inferior at y+=11.
But how do I calculate the value of y+?
From what I understood, I am supposed to estimate a value of the free convection velocity, but I will also need an estimation of the friction coefficient, and also a way to calculate U_tau, beeing the friction velocity.
I think that these parameters are function of geometry, turbulence, and so on, but I guess I could find a summary somewhere.
Do you know where I could find some tutorial or something?
